AThis invention relates vto improvements in rovide means for automatically raisinga loa at one station, transferring the load to another station, lowering the load, raising the lo'ad carrying device, transferring'the load 'carrying device to the first station.v and lowering it to be reloaded. j

Other objects will appear from the hereinafter description. y x 'v '()ne embodiment of my inventio'n'is set forth in the following description and illustrated in the accompanying drawings which form a part of this' application.

Referring to the drawings inwhich the samereference character indicates the-same part in the'several views, Figure 1 shows one type of my apparatus with the telphergat say the 'homestation and' the load carrying dev ice, in this case a bucket, in its lowered posit'ion` with the telpher switch in'position to l y move the telpher to the right.

Fig. 4 is a similar view to Fig. 3 with the bucket in its lowered position. Fig. 5 is a diagrammatic view of certainof the electric wires. v 1 1 The part marked' 1. on the drawing represents the track on which the telpher travels.

On this hoisting rope near tle ripper; end thereof'is the enlargement or stop 21a, the lower end of tlie rope being provided with another stop 2lb. 22 is. the means for carrying the load', in this instance a bucket, having ivoted thereto the bail 23 which. is secure to the lower end of the' hoisting ro e 20.

24 is a catch pivoted to t e bail and hasa hook 25 which engages the edge ofthe bucket and revents the bucket from turning over and Aumping its load. This catch 24 1s provided with a finger 24a which comes in con* tact with the pivoted switch 26 and o erates the switch when the bucket is lowere at the home station.l 27 is a pin at an outlying station against which the finger 24a strikes and causes the catch 24 to reiease from the bucket when the bucket is lowered so that it may be dumped, as shown in Figs. 3.and 4. -I

We will now describe as .much of the electric wiring asis necessary to a thorough (understanding of our invention.' This is shown in Fig. 5 of the drawingdy l 30 The electric mains are represented by the plus and minus signs'. The plus main leads to the'trolley wire and the negative to the 'ground return. The plus wire is connected to the binding post or terminal 26a.

28 is a pivoted switch to which the wire 29 leadingto the main trolleyY (wire 2' is connected.

Coiisidering the conditions as shown on this v diagram, at vwhich time thebucket will be in the lowest' position, if 'we start at the 40 .trolley wire and trace the current down 4through the trolley pole E to the point marked 30, it will be 'seen`that the current can travel in either direction. That is, from theupoint 30 to the terminal h, or 'from 36to the terminal c.

the` copper plate or disk 7u to the terminal t',

through the armature H of the hoist motor,

' then tothe terminal g across the other copper plate y" to the terminal f, thence through the field F of the hoist motor to terminal 17,

to terminal 15 and then -through the switchh the iexible connection 31,. lthrough the wlre 32, and back to the ground arm 11, labro througlh the wir 33. -lt will th'ns be seen that t e current is passing throu h the hoist motor, andthe directichiln' whic the motor isy running will determine whether the load (i5-at c the current will pass-to d, through (the oint.

If it .be V assumed that the, current passes from 30 to h, it will pass across cop erplate e, thence to-thearmature of the telp er motor T to terminal b', through the cop er plate e to terminal a, thence through the eld G of the telpher motor to the terminal l then to terminal m, then through*y the 7U lever arm 34, through the flexible connection, through the wire 23 to the terminal 16. But since the lever arm 11 is not on this terminal, it will be noted that the current stops at this Therefore when the lever arm 11 is 75 1n the position showniin Fig., 5, the current can pass through the hoist dcircuit, and the o nl}T time when the current can ass through the telpher circuit is when the lever arm l11 is on the terminal 16. s0 It will also be noted that if the arm 11 is on the terminal 16, the hoist ,cannot move in either direction, for the circuit will be open at the terminal l1. if the lever arm is on the terminal 16. Of course, it is self-evident 35 that the switch if turned will reverse the hoisting motor; likewise if the telpher switch is reversed 90o, Vit will reverse thetelpher motor, for it is evident that should the first named switch be reversed 90, the lever arm 90 which is on the terminal 15, as shown-in Fig. 5 will be moved onto the terminal 17. It will also be noted that the copper plate which now connects the terminals f and g will then connect the terminals g and l1.. Likewise the disk will connect f and i. Thus it will beseen that the direction of the current through the armature has been 'changed and the .motor has thus been rcversed. A similar explanation applies to the/ telpher switch. n,

he apparatus-as afwhole operates as fol-v lows: We will assume that the first position of the apparatus is as shown at Fig. 1, in. which the bucket is down', a load thereinand 105 the telpher at the home station with the switch 5 turned to .movethe telpher to the right when the current is thrown therein,

i and that the hoisting motor switch is turned sothat the bucket will be hoisted. Upon making the contact, which maybe done by turning the lever 26 so -that'the switch 2S willcome in contact with the terminal 26%. the* hoist motor will o erate to. raise the wbucket to the position s own in Fig. A2, the 1615 sto 21?. comes in contact with the arm 13 an turns the switch to the position shown in 2, so that the lever'armll is on'the terminal'l. When in this position, as before described, vthe telpher motor is cut in and the hoist motoris Qcut out because the lever 11 is not on either oneof the terminals 15 or 17 "The telpherisnow thrown in and travels to the right .towards the position shown in Fig; 3. When the arm 5 strikes 125 the lever 7, the said arm is thrown to the position shown in Fig. 3 and the direction of thecurrentof the telpher4 will be changed,

kbut as the telpher travels to this position the' varrrl 14 comes 1n contactwitn the stop 19 and 130l l the catch 24-has come in contact with the theswitch is moved to the position shown Fig.v 3 with the lever arm resting on the contact 17 ln this position the telpherlis out termed the hoist to lower. vThis :figure shows,

out because the leverarm 1.1 is off the contact 16 and thehoist is cut in and the lever 11 resting on `the terminalv 1,7`.will causel the rope and bucket Vwhich may be generally the bucket lowered with the stop 21%; justin contact with the lever 13. The arm 24 of stop 27 'and releases'the bucket uso that the bucket is dumped. The bucket continuesto be hiwered, however, vuntil the loweri apparatus is stopped. ,As the. bucket continues to lower, the; stop 21a being in contact withl the-arm 13 will throw the switch arm 11 from the `'contact 17 to the contact 15, as shown in Fig- 4 of the drawing. When. the parts are. in this position/the hoisting motor will be` moving 'to raise the bucket, and the bucket' will continue to rise until vthe stop 21b comes in contact with the arm 13 when 1t will move" the .switch .arm` 11 is moved ofi of the conget 16, stoppinglthe telpher and moved to c contact 17, W ereupon the hoist' vmotor 1 1s put in -o eration to lower the buc et and the bucket, owers until the stop 2l`comes in contact-with the lever 13, and throvs'the arm 11 oifof the contact .17 to 15, `andgwhen ngler v.24 strikes the lever 26, itwill move t ef switch 28 off of the terminal 26EL and entirelylcut out 'or break the circuit so that 'there is no current passing through any of the wires.`

It is understood thatnected to the switch 2S so that they maybe moved together. l

While we have shown, as before stated,

.one type of the apparatus for doing the work intended, |yet it is -to be understood that variters Patent is:

the lever 26 is con-v `ous other types of apparatus may be used without departing from-the scope of our in- I vention. l
